Decoding Famous Hacks: A Historical Perspective


Crypto exchange breaches have become a recurring theme, causing investors' vulnerability and eroding industry trust. So, which crypto exchanges have been hacked? Let's delve into some of the most famous hacks and their effects.

The Numbers: How Many Crypto Exchanges Have Been Hacked?

Data gathered by Crystal Blockchain and Cointelegraph reveals a sobering statistic. From 2011 to 2020, the total amount of funds lost in crypto exchange hacks exceeded $15.6 billion. Over 50 exchanges were victims, with several facing multiple breaches. A record number of 19 crypto exchanges suffered attacks in 2019 alone, though this number has decreased in recent years.

The year 2021 brought more than 20 major incidents, each resulting in at least $10 million in digital currencies stolen from a crypto exchange or project. At least six instances saw hackers getting away with more than $100 million.

In 2022, Chainalysis identified $3.8 billion in cryptocurrency hacks. This represented a 15% increase from 2021, which saw losses of $3.3 billion, and a dramatic rise from the $0.5 billion stolen in 2020.


Here's a quick answer to the question - how many crypto exchanges have been hacked? While the exact number is uncertain due to undisclosed incidents, we have the infamous 7 listed here.

Mt. Gox

  • Date: The hack began on February 7, 2014.
  • Amount stolen: 744,408 bitcoin from Mt. Gox customers and 100,000 from the company itself, equivalent to $460,000 at the time and over $20 billion now.

Mt. Gox, once the largest cryptocurrency exchange, fell victim to a devastating hack. Hackers stole Mt. Gox's hot wallet private keys from a wallet.dat file, and additional coins were stolen from other exchanges. Chaotic aftermath ensued as the hacker continuously emptied wallets, with the system mistakenly interpreting the spending as deposits. This resulted in some users receiving up to approximately 40,000 extra BTC. Mt. Gox declared bankruptcy, and the legal battle for creditors' compensation lasted for years. However, recent progress indicates a step closer to asset recovery.


  • Date: January 2018.
  • Amount stolen: Over $500 million worth of digital coins.

Coincheck, a Tokyo-based exchange, suffered a major breach that sent shockwaves through the crypto industry. Hackers exploited Coincheck's security lapse, storing customer assets in a vulnerable hot wallet instead of a more secure cold wallet. Although the stolen NEM coins were identified, the owners remained unknown, casting doubts on the hackers' ability to cash them out. Initially, Coincheck promised to reimburse users but later adjusted its stance, only partially reimbursing the stolen funds. Coincheck has since been acquired and has taken measures to improve security protocols.


  • Date: September 26, 2020
  • Amount stolen: Over $280,000,000 worth of cryptocurrency.

In 2020, KuCoin experienced a security breach resulting in significant financial losses. Hackers gained access to the exchange's hot wallets, leading KuCoin to transfer remaining funds to new wallets and freeze customer deposits and withdrawals. Through collaboration with law enforcement agencies, the stolen funds, spread across various cryptocurrencies, were later recovered. This incident highlighted the importance of swift action and cooperation in mitigating the impact of hacks.


  • Date: February 8, 2018
  • Amount stolen: $170,000,000

BitGrail, an Italian cryptocurrency exchange, suffered a hack resulting in the theft of 17 million units of Nano (XRB), valued at $170 million. The exchange temporarily suspended all transactions and reported the incident to authorities. Controversy arose as BitGrail's owner, Francesco Firano, blamed the Nano development team and suggested modifying the ledger to cover the losses. This proposal was rejected, leaving affected users seeking reimbursement through BitGrail Shares (BGS) tokens.


  • Date: December 5, 2021
  • Amount stolen: $196 million

In December 2021, BitMart fell victim to a security breach, resulting in the loss of $150 million worth of cryptocurrencies. The hack targeted BitMart's ETH and BSC hot wallets, leading the exchange to suspend withdrawals and initiate a thorough security review. The stolen funds were sent to an Ethereum mixing service, complicating tracking efforts. BitMart has since suspended all deposits and withdrawals, pledging to reimburse affected customers.


  • Date: March 25, 2019
  • Amount stolen: $100,000,000

Coinbene, a cryptocurrency exchange platform, faced allegations of a hack in March 2019. While the exchange claimed to be undergoing maintenance, evidence suggested a security breach. Outgoing transactions involving multiple tokens raised suspicions of a cover-up. Coinbene's website has since become inaccessible, indicating a potential closure.


  • Date: August 19, 2021
  • Amount stolen: $80,000,000

Japanese exchange Liquid encountered a security breach, resulting in the movement of over $80 million worth of digital assets from the platform. Liquid promptly suspended withdrawals and deposits to investigate the incident. The stolen assets included BitcoinTron, Ether, and ERC-20 tokens. Liquid has since reinforced its security measures and compensated affected users.

Lessons Derived from Crypto Exchange Hacks


These incidents serve as cautionary tales, emphasizing the importance of robust security measures and proactive actions to protect user funds. Let's explore the key lessons learned from these notorious attacks.

Enhancing Security Measures: A Crypto Exchange Development Necessity

Crypto exchanges must prioritize security to maintain user trust. Implementing stringent security protocols is crucial for safeguarding user funds. This includes:

  • Multi-Factor Authentication (MFA): Exchanges should require multiple layers of authentication to access user accounts, reducing the risk of unauthorized access.
  • Regular Security Audits: Conducting frequent security audits and vulnerability assessments helps identify and address potential weaknesses in the system, fortifying defenses against cyber threats.
  • Cold Storage: Utilizing cold storage wallets, which are offline and less susceptible to hacking attempts, provides an added layer of protection for cryptocurrencies.

The Role of Regulation and Compliance in Preventing Crypto Exchange Hacks

Regulatory frameworks play a vital role in the crypto industry, providing a framework for security and protecting investors. Exchanges must adhere to industry standards and regulations, implementing robust Know Your Customer (KYC) and Anti-Money Laundering (AML) procedures. Collaboration between exchanges, regulators, and law enforcement agencies is essential to mitigate risks and combat fraudulent activities effectively.

Educating and Empowering Investors: Mitigating the Risk of Crypto Exchange Hacks

Education is key to safeguarding investments in the crypto space. Users must be aware of potential risks and emerging threats. Exchanges can contribute by providing educational resources and promoting safe trading practices. By staying informed about the latest security measures, users can make informed decisions and protect their assets.

The Significance of Multi-Factor Authentication and Cold Storage

Adopting multi-factor authentication adds an extra layer of security to user accounts. By requiring multiple authentication methods, such as passwords, biometrics, or one-time codes, exchanges can significantly reduce the risk of unauthorized access. Additionally, storing cryptocurrencies in cold wallets, offline storage solutions, ensures that funds remain safe from online threats.
